A Queens high school sells students books they are required to read — and runs a book store that charges up to $13 for “To Kill a Mockingbird” and $15 for an illustrated tome on Greek myths, The Post has learned.

The practice goes against city and state rules.

Unlike most public schools, Maspeth HS does not provide all the books that students are assigned to study. Instead, the kids must get many books on their own — by either buying them or borrowing one from a library, they said.

Students are told they must use only a specific edition of the book — and those are conveniently sold in the school store.

Maspeth sells 45 different books, mostly for English, plus several for other classes such as social studies and chemistry. Prices start at $2 for Machiavelli’s “The Prince” and $3 for Dickens’ “Tale of Two Cities.” Six books cost $10 each, including “Brave New World,” “Black Boy,” and “The Great Gatsby.”

Students said they fork over about $25 to $50 a year on books. Those who can’t come up with the cash are advised to privately tell their teachers.

“If people have financial problems, they say, ‘Speak to me after class,’” a senior said.

About 69 percent of Maspeth students come from low-income families.

Students said teachers urge them to buy their own books so they can write notes in them.

Most kids buy them at the school store.

“It’s better than going to Barnes and Noble,” a sophomore said.

But the practice stunned veteran educators.

“It’s not right to put a kid on the spot like that. It’s embarrassing and humiliating. To do that to a teenager is horrible,” a teacher said.

Students “should not need to divulge their economic status” to get a required book, said David Bloomfield, a Brooklyn College and CUNY Graduate Center education professor.

Bloomfield and other experts say Maspeth appears to violate state education law, which says public schools have a duty to purchase and loan textbooks to all children for free.

An NYC Chancellor’s regulation states: “Materials and textbooks supplied by the Department of Education for use in classes . . . shall not under any circumstances be sold, nor shall any charge for them be made to the students.”

The DOE would not disclose how much money Maspeth raises in book sales, saying only that proceeds go into the school’s general fund.

“No students at this school are ever required to purchase class books,” said spokeswoman Devora Kaye.
